Abstract With advances in automation, industry seeks for optimization while new products are developed and manufacturing processes are becoming smarter. In this sense, virtual manufacturing validations have been demanded for reducing the cost with physical prototypes, ensuring ergonomically safe processes and increasing the quality of processes by emulating it realistically, levering automation utilization in industry environments with a faster and safer manner. By that, this research proposes the use of Tecnomatix Siemens® PLM software for process simulation of 7050 aluminum drilling, material which is widely used in aerospace industry, allowing the evaluation of complexes scenarios with multi-robot integration and its conditions and variables, in order to improve the machining process and its aeronautical structural assemblies. Thus, this research provided a relevant contribution regarding the analysis of main process parameters to obtain an efficient sequence of drilling, its productivity and ergonomic conditions.

Completely digital workflows for the fabrication of implant-supported removable restorations are not yet common in clinical dental practice. The aim of the current case report is to illustrate a reliable and comfortable workflow that reasonably merges conventional and digital workflows for the CAD/CAM‑fabrication of implant-supported overdentures. The 53-year old patient was supplied with a digitally processed complete denture in the upper jaw and, simultaneously, with an overdenture supported by four interforaminal implants in the lower jaw. The overdenture included a completely digitally processed and manufactured alloy framework that had been fabricated by selective laser sintering. The case report indicates that digital manufacturing processes for extensive and complex removable restorations are possible. However, as it is currently not yet possible to digitally obtain functional impressions, future developments and innovations might focus on that issue.

Sophisticated robotic applications require systems to be reconfigurable at the system level. Aiming at this requirement, this paper presents the design and implementation of a software architecture for a reconfigurable real-time multi-processing system for multi-robot control. The system is partitioned into loosely coupled function units and the data modules manipulated by the function units. Modularized and unified structures of the sub-controllers and controller processes are designed and constructed. All the controller processes run autonomously and intra-sub-controller information exchange is realized by shared data modules that serve as a data repository in the sub-controller. The dynamic data-management processes are responsible for data exchange among sub-controllers and across the computer network. Among sub-controllers there is no explicit temporal synchronization and the data dependencies are maintained by using datum-based synchronization. The hardware driver is constructed as a two-layered system to facilitate adaptation to various robotic hardware systems. A series of effective schemes for software fault detection, fault anticipation and fault termination are accomplished to improve run-time safety. The system is implemented cost-effectively on a QNX real-time operating system (RTOS) based system with a complete PC architecture, and experimentally validated successfully on an experimental dual-arm test-bed. The results indicate that the architectural design and implementation are well suited for advanced application tasks.

And Performance

To protect the security of critical data and application system, generally, many companies or departments use a parallel way of intranet and internet. Because every kind of security technology has its limitations, traditional security products such as firewall, VPN, data encryption, intrusion detection and network vulnerability scanning can not completely solve various security problems in information exchange between different networks. It is not able to meet all the security needs of critical networks and security data with the general products only. The way of data exchange of most of the existing products of "GAP" is mainly logic isolation .This paper describes a design and implementation of a hot switch circuit card in way of physical isolation .The data exchange mode of this circuit card is a half-duplex which can physically completely isolate intranet and internet. Through functional test and performance test, we can draw a conclusion that the circuit card can effectively achieve our demand of data exchange between different networks.

Filament winding and fiber placement are low-cost, fast, and suitable processes for manufacturing composite grid structures. Resulted structures are high quality products. They have the advantage of carrying heavy structural loads as well as light structural weight. Composite Grid Structures (CGS) are manufactured with varying geometries such as circular (cylindrical and conic) and flat. They are applied in hightech industries including aerospace industry. In this paper, the manufacturing processes of these structures and their various aspects (including winding method, mandrel material and curing method) are reviewed and compared in detail.

Growth of nature is an additive process that gives sustainable existence to the structures developed; on the other hand, traditional manufacturing techniques can be wasteful as they are subtractive. Additive manufacturing produces almost nil waste and accordingly preserves raw materials resulting in cost reduction for the procurement of the same. It will also cut down on the carbon emissions that are usually generated from industrial manufacturing. Additive printed objects are lighter as well, making them more efficient, especially when used in the automobile and aerospace industry. Further, the intrinsic characteristics and the promising merits of additive manufacturing process are expected to provide a solution to improve the sustainability of the process. This chapter comprehensively reports on various additive manufacturing processes and their sustainable applications for green technology. The state of the art, opportunities, and future, related to sustainable applications of additive manufacturing have been presented at length.

Technological Level

El presente proyecto se realizó con la finalidad caracterizar el nivel tecnológico de la industria aeroespacial de Ensenada, B.C. México., en sus procesos de manufactura para establecer áreas de oportunidad y determinar su impacto en la competitividad. Se llevó a cabo una investigación cuantitativa, de tipo descriptivo para establecer el nivel de automatización, los cuales se aplicaron en encuestas directas en visitas industriales (Ovalle, et al., 2013). Se entrevistaron siete empresas en donde se determinó sus diferentes estrategias para la compra de nuevas tecnologías, incluida la automatización. Se identificó que las empresas adquieren la nueva tecnología a través de proveedores previamente seleccionados y en algunos casos cotizando a nuevos proveedores. La vigilancia tecnológica se realiza preferentemente en catálogos o con la visita de proveedores; también por recomendaciones de los clientes, o visitando ferias o misiones tecnológicas. Se registró que algunas empresas cuentan con la asesoría de centros de investigación y que seleccionan la nueva tecnología mediante los criterios de estandarización y adaptabilidad al proceso, seguido de precio y marca. Los mayores niveles de automatización se registraron en la comunicación, seguido de la etapa de proceso de producción, y la del abastecimiento de materiales.
